Double-loop control system is used in the case of different temperature needed for the dynamic and fixed template of the die. According to the different temperature requirements of the two templates, the temperature of the two loops and the flow rate of the pump are controlled. At the same time, the power supply of the cooling water is connected with the main power supply in the same junction box to reduce the size of the whole machine.
The multi-loop control system consists of several separate loops, each of which is used to control the different temperatures required in the product forming stage. Therefore, the system can achieve perfect results in controlling the technical products of the die and special process with complex structure.
Oil heater is a large-scale hot oil temperature control equipment. Its main characteristics are that it can obtain room temperature to 350 C under low operating pressure, large pump flow and high heating power. Widely used in petrochemical industry, plastic rubber industry calendering, mixing, vulcanization, textile printing and dyeing industry heat setting, drying, printing industry composite, film coating, non-woven calendering heating, etc. The company is a professional oil heater manufacturer, introducing advanced German technology, optimizing system design, providing customers with low-cost and high-quality temperature control equipment.
Mold temperature is high, melting material cooling is slow, density is high, shrinkage is large, especially for crystalline material because of high crystallinity and large volume change, so shrinkage is larger. Mold temperature distribution is also related to internal and external cooling and density uniformity of plastic parts, which directly affects the shrinkage and direction of each part. In addition, holding pressure and time also have a greater impact on contraction, while large pressure and long time have smaller contraction but greater directionality. The injection pressure is high, the melt viscosity difference is small, the interlaminar shear stress is small, the elastic rebound after demoulding is large, so the shrinkage can also be reduced appropriately, the material temperature is high, the shrinkage is large, but the directivity is small. Therefore, adjusting die temperature, pressure, injection speed, cooling time and other factors can also properly change the shrinkage of plastic parts.
According to the material and product quality of injection moulding products, such as pet, ordinary, PC oil temperature, good stability.
According to the required temperature, there is balance performance.
